Re: Pontoon boat listing to the Starboard side
Welcome to iboats.
If it came with a trailer pull the boat, have someone start driving(5'-6') then stop suddenly then put your ear on the tube, if there is water you will hear it slosh.
If it does have water you will need to find a welder and have the tube drained and repaired.
Correct method is to tip the boat slightly back on the trailer and drill at the rear of each chamber to drain, if you get a little air in while it is draining it goes alot faster, then get 3-4psi in each tube section, one at a time, and strt sprayong with soapy water, mark and repair all leaks.
The leak could be anyhwere, I normally find them at the back of the rear brackets, but as I said it could be anywhere.
